ok ok. so i get home today, and i see that my mandarin is no longer swimming around in the tank, my yellow tang's color looks as if he is stressed out, i have a closed and open brain's and look shrunken, and so i figured something must not be right i decided to check water levels and my results were
ph. 8.0
nitrate 20
alk. 1.7
nitrite between .05 - 0.1
phosphate 0.5
Calcium 560
salinity 1.028
temp 82
so now my question is what is the fastest and safest way to fix this levels, i'm thinking of 15% water change ASAP, add activate charcoal, some phosphate removal pebbless. what other suggestion do u guys have... any will greatly be considered and appreciated... thanks
